A long time in the making
Curiosity landed in Gale Crater on August 6, 2012. More than 12 years later, the rover has driven over 21 miles (34 kilometers) to ascend Mount Sharp, which is within the crater. The feature’s many layers preserve millions of years of geological history on Mars, showing how it shifted from a wet to a dry environment.

Perhaps one of the most valuable samples Curiosity has gathered on its mission to understand whether Mars was ever habitable was collected in May 2013.

The rover drilled the Cumberland sample from an area within a crater called Yellowknife Bay, which resembled an ancient lake bed. The rocks from Yellowknife Bay so intrigued Curiosity’s science team that it had the rover drive in the opposite direction to collect samples from the area before heading to Mount Sharp.
Since collecting the Cumberland sample, Curiosity has used SAM to study it in a variety of ways, revealing that Yellowknife Bay was once the site of an ancient lake where clay minerals formed in water. The mudstone created an environment that could concentrate and preserve organic molecules and trapped them inside the fine grains of the sedimentary rock.

Freissinet helped lead a research team in 2015 that was able to identify organic molecules within the Cumberland sample.

The instrument detected an abundance of sulfur, which can be used to preserve organic molecules; nitrates, which are essential for plant and animal health on Earth; and methane composed of a type of carbon associated with biological processes on Earth.

“There is evidence that liquid water existed in Gale Crater for millions of years and probably much longer, which means there was enough time for life-forming chemistry to happen in these crater-lake environments on Mars,” said study coauthor Daniel Glavin, senior scientist for sample return at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in a statement.

The U.S. and China are copying each other, giving rise to memes and mockery (4/13/2025)
President Donald Trump wants to bring back American manufacturing in ways that would reshape the United States economy to look more like China’s. The campaign, which has led to a rapidly escalating trade war with China, has given ample social media fodder to Chinese and American observers alike.

Announcing a series of sweeping tariffs in a move dubbed “Liberation Day,” Trump said last week that it will lead factories to move production back to American shores, boosting the U.S. economy after “foreign leaders have stolen our jobs, foreign cheaters have ransacked our factories, and foreign scavengers have torn apart our once beautiful American dream.”

In a Truth Social post Wednesday, Trump announced that he is raising tariffs on goods imported from China to 125%, up from the 104% that took effect the same day, due to “the lack of respect that China has shown to the World’s Markets.” Higher targeted tariffs on other countries have been paused for 90 days, although the 10% baseline tariff will remain in place for all countries.

Meme-makers and Chinese government officials have in recent days begun pointing out the irony of Trump’s tariff-driven manufacturing pivot through AI-generated satire and political cartoons that have percolated online, with many American users boosting the jokes.
